how do you upgrade the ship consoles from ensign stations to lieutenant stations and so on so that my Lieutenant BO can use their upgraded skills? IE: Jamming Sensors 2 ! As it keeps saying my BO can't use at this Ensign Station?

When you get to Level 11 and beyond, the type of ship you get will determine the consoles. Cruisers = engineers escorts = tactical science = well..guess. As you get higher in rank you will get access to higher ranking stations. I recommend looking at the different ship classes at the computers in the Shipyard at Earth spacedock, or looking at the ship tier chart floating on the net

thank all for help! no point in promoting Bo crew till you get bigger ships then!
I Use a cruiser at LT commander level 3 at moment and have 3 lieutenants on my crew.
all stuck at ensign apart from 1 using their lieutenant skills.

Promoting crew members can give access to their ground skills, which may or may not be useful, depending on whether you find ground missions challenging at all.
